Kol by Vi Voxley

Forever is no time at all, sometimes.
Jackie Hooper is all out of time. An incurable illness at her side, she’s trying to make the best of the opportunities she has left. Getting abducted by a Nayanor warlord was not on that list of things to do. But then again, spending your last moments with the hottest man in the universe can’t be all bad… right?
Kol-Eresh has found what he has been looking for – the perfect mate. Or so he thought. Her death is not something that he will allow, yet options are slim for the alien lord. Good thing he’s known for making something out of any decent apocalypse.
With the Eternals on the hunt, the Nayanor elders obsessed with curing the land of the weak, Kol has more to worry about than just losing Jackie to a disease. He has too much to fight, too much to overcome, but then again, he’s always been at his best when things are impossible.
